Abstract: An infrared headlight useful in a night vision system may be made with an infrared emitter positioned in a reflector. The radiation source is associated with a filter body which has a first filter layer part and a second uncoated part. The two parts are designed so the radiation transmitted through the uncoated part strikes a different area of the reflector than the infrared radiation transmitted through the filter layer. The two regions of the reflector may have differing reflective characteristics.

Abstract: In the metal halide high-pressure discharge lamp for stage, film and television lighting systems and for projection technology and effect lighting, the discharge vessel contains dysprosium and cesium as fill metals for the metal halides. Optimum results for dimmability, arc instability and color rendering are achieved if the fill additionally includes 0.12 to 3.8 ?mol of vanadium and if appropriate 0.05 to 1.0 ?mol of zirconium per ml of vessel volume. These metals achieve improved color rendering, in particular red rendering, with an Ra of from 70 to 95 and an R9 of from 45 to 90.

Abstract: The multi-color light lamp has a base divided into a plurality of segments. The three segments are spaced at 120 degrees. More or less segments can be used. An LED is positioned in each segment, the LED in each segment emits a color distinct from the light emitted by the LEDs in the other segments.

A light pipe is operatively associated with the LEDs in each segment for directing emitted light away from the base. The LEDs (preferably two per segment) are mounted upon a thermally efficient printed circuit board such as a flex-on aluminum board.
